Alzheimer’s disease: the involvement of the oral microbiota has been confirmed

Alzheimer’s disease could be the consequence of chronic inflammation of neuronal tissue caused by the colonization of bacteria from the oral microbiota which produce toxic proteins called “gingipains”. Therapeutic applications are already being considered.   A link was already established...

Sex-dependent effects of nicotine on the microbiota and the brain

The effects of nicotine on the intestinal microbiota, bacterial metabolism and the gut-brain axis are thought to be sex-specific, according to American researchers.   For the first time, a study has explored the sex-specific impact of nicotine on the microbiota and neuroactive chemical si...

Fecal transplant against Parkinson’s disease

Parkinson’s disease is the second most common neurodegenerative disease. All that can currently be done is alleviate its symptoms. Faced with the failure of current treatments, a Chinese team conducted a non-clinical study to explore the involvement of the microbiota and the promising effects of fec...

Parkinson's disease

For roughly 15 years, it has been hypothesized that Parkinson’s disease does not originate exclusively in the brain, but also in the intestines. However, the potential biological mechanisms involved remain to be elucidated.

Multiple sclerosis

The intestinal microbiota may become a target for therapy in the fight against multiple sclerosis (MS). The results of several studies showed its involvement in the onset of immune anomalies associated with myelin loss.
